The nodes are randomly changingtheir Position and so, performance is suffered. In this paper we discuss about the effect ofscenario on the performance of Reactive /On-Demand Routing Protocols AODV (Ad-Hoc On-Demand Routing) we have taken three different scenario parameter for AODVand examine the result on the basis of packet delivery ratio (PTR), throughput and end-to-end delay. The result shows that AODV is best for one scenario environment. Thusscenario also affects the result of any protocols.Key Terms-Mobile Ad hoc Network (MANETs), Routing Protocol, Simulation, PacketDelivery Ratio/fraction (PDR/PDF), throughput and average to end-to-end delay.I. INTRODUCTIONA mobile ad hoc network (MANET) is self-configuring and infrastructure less network. Itconsists of a collection of wireless mobile nodes that are capable to communicate with 33

The objective of this paper is to examine the effect ofdifferent scenarios environment on the performance of routing mechanisms like averageend-to-end delay, routing overhead, throughput, and packet delivery ratio specifically forMANETs. In MANETs routing protocols are broadly classified as Reactive andProactive. It is aimed to evaluate the effects of scenario on the performance of on-demand reactive protocol AODV (Ad hoc On-demand Distance vector) on the simulationbasis. This simulation is done by using widely recognized and improved networksimulator NS-2 version 2.29.3 for MANETs, with appropriate modification on NS-2 filesand TCL scripts for fair performance evaluation [5].II. METHODOLOGY On the bases of previous studies [5][6][7] we saw that the performance of routingprotocols are Affected by scenario parameter like scenario size, pause time and so on. Inthese paper we have discussed, the effect of scenario parameter on the performance ofMANETs reactive routing protocol AODV. The evaluation of performance of MANETs routing Protocol AODV are based ondifferent Scenarios such as network Size, Pause Time, Max Speed. The following are themetrics which we have used for the performance analysisa. Packet Delivery Fraction (PDF) This is the ratio of total number of packets successfully received by thedestination nodes to the number of packets sent by the source nodes throughout thesimulation. A high value of PDF [2][3][6][7].b. Throughput (bps) Throughput represents the total number of bits forwarded to higher layers persecond. A high value of PDF indicates that most of the packets are being delivered to thehigher layers and is a good indicator of the protocol performance [5].c. End to End delay This is defined as the average delay in transmission of a packet between twonodes. A higher value of end-to-end delay means that the network is congested and hencethe routing protocol doesn’t perform well [ 3][6][7]. 34

EXPERIMENTAL RESULT Table 1 Effect of different Network size Parameters Values Traffic type cbr No. of nodes 50 250*250m,500 * 500 m Network size ,1000*1000m Maximum speed of 8m/s nodes Pause time 1ms Simulation time 200s Figure 1 Present the comparison table and graph of different sennerio parameter on the bases of PDF, throughput, End To End Delay. III(a). In these cases we have seen that the performace of AODV is better for250*250m network size because the PDF and throughput are high but delay was less ascompaire to other two.and 500*500m and 1000*1000m are giving approximate samePDF and Delay but throughput was very poor in 500*500m. So we can say thatperformance of AODV according to network size 250*250m was best and in 500*500mnetwork size performance was poor. Table 2 Effect of different Max speed Parameters Values Traffic type cbr No. of nodes 50 Network size 500 * 500 m Maximum speed of 10m/s,15m/s,20m/s nodes Pause time 1ms Simulation time 200s 35

When Max speed is 10m/s and 15m/s AODV give the good PDF butthroughput is less and delay was high. but in 20m/s max speed give a good PDF andThroughput but delay was very high than other two. Table 3 Effect of different Pause time:- Parameters Values Traffic type cbr No. of nodes 50 Network size 500 * 500 m Maximum speed of 8m/s nodes Pause time 4ms,8ms,15ms Simulation time 200s Figure 3 Present the comparison table and graph of different sennerio parameter on the bases of PDF, throughput, End To End Delay 36

In the case of different Pause time the PDF for 4ms,8ms and 15ms areapproximatly same but throughtput for 4ms and 15ms are also approximatly same but for8ms it is much better than other, also the delay is very high for that but aproximatlly samefor 4ms and 15 ms.IV. CONCLUSION The combination of parameters are very important to increase the performancebecause all factor had affected the result and performance. Performance of AODVdepended on the numbers of nodes but also on the scenario parameters like, when thenetwork size is 250*250, pause time is 1ms and Max speed is 8m/s AODV is give betterresults as compare to other scenario environment.REFERENCES 1 2 2 31.
